Reviews
Recommendations
Almost two years I’ve worked along side of Joost and while we are worlds apart it always worked very well. Joost is a firm Scala believer whereas I’m from a different background but we could always find a middle ground that elevated us both. Joost has the capability to think out of the box and design complex systems effortless, thus keeping the team on the right track. He will also not shy away from a nice discussion about solutions but is willing to listen when ideas are good.

Scala. Joost has an evangelistic passion for Scala, which is reinforced by his sound knowledge of Java. In particular, he contributed to the teams vision of progressively transitioning from Java to Scala technologies by investigating remote integration technologies. Joost was productive and focused in his development duties but relaxed and willing to share a joke at the same time. He fitted into the dynamics of the agile team well demonstrated by his being occasionally outspoken on technology choices (involving Java and Spring in particular) and being adaptable to the preferences of the team. The drive and passion Joost has for his work would benefit any team looking for a developer.

Joost is a very dependable software engineer who writes code of high quality. When confronted with a complex problem, he won’t stop until he gets to the root cause. He easily adapts to his working environment and is familiar with a lot of different technologies.
